TUBULAR LANTERN.

SPECIFICATION forming part of Letters Patent No. 401,490, dated April16, 1889.

Application led June 13, 1887. Serial No. 241.150. (No model.)

To all whom t may concern:

Be it known that l, ELIAS O. GLAZIER, of the city of Rochester, in thecounty of ilionroe and State of New York, have invented a new and usefulImprovement in Tubular Lanterns, of which the following is aspecification.

This invention relates to that class of tubular lanterns or lamps whichcontain a tubular frame, in the lower portion of which the oil- Io potand burner are supported, and which are provided with a loose globewhich can be raised from the burner when access is required to thelatter for turning the wick, lightingand extinguishing the lamp, andother manipulations.

The object of my invention is to provide the lamp with a simple andconvenient means for raising the globe and for sustaining it in anelevated position, and for guiding it back 2o to its seat on the lowerportion of the lamp.

My invention consists of the improvements which will be hereinafterfully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a sectional elevation of alamp provided with my improvements. Fig. 2 is a fragmentary sideelevation of the globe-lifting device on an enlarged scale. Fig. 3 is ahorizontal section in line @c cc, Fig. 2. Fig. 4 is a perspective 3oView of the globe-lifting device.

Like letters of reference refer to like parts in the several figures.

The lamp illustrated in the drawings, to which my invention is applied,is a tubular 3 5 globe street-lamp, the general construction of which iswell known and which is described and illustrated, for instance, inLetters Patent No. 218,917, granted to Lewis F. Betts August 26, 1879.

4o In .said drawings, A represents the postsocket at the base of thelamp structure; B B, the air-tubes; O, the lamp-top; D, the removableair-chamber which envelops the oil-pot cl, provided with a burner, d,andF the globe.

The latter can be raised in the lamp-frame, so

that the burner can be exposed and the airchamber D be freed from theweight of the globe and be removed from the lamp-frame with the oil-potand burner, if required. All of these parts are old and well known.

F represents a lifting-lever pivoted to the inner side of one of theair-tubesBin bracketbearings f f, secured to the same. The inner arm, g,of the lever F extends toward the base of the globe, and carries at itsinner end a hook` or globe support, G, in which the globe rests andwhich is hung loosely to the inner end of the lever F. The hook or globesupport G bears partly against the outer side of 'the globe and extendsunderneath the base of 6o the globe and upwardly on the inner side ofthe latter, as clearly represented in Fig. 2. The outer arm, h, of thelever F rests snugly against the side of the tube B, and is preferablyconstructed of spring metal or other elastic material. In the normalposition of the lever F its outer arm, h, stands inwardly of thecrown-lineiA of the tube B, as represented in Fig. 3.

When the globe rests on the removable air- 7o chamber D, as representedin Fig. 1, the outer arm, h, ot' the lifting-leverF is elevated. When itis desired to raise the globe, the outer arm,

h, of the level.` F is depressed, thereby raising the inner arm, g, hookG, and the globe rest 75 ing thereon. The upper end of the globe isguided during this movement in the lamp-top C. Just before the globereaches its highest position the outer arm, h, of theleverF passes thecrown-line 'i of the tube, and then springs 8o inwardly to the positionrepresented in Fig. 2. The lever F, in bearing against the convex sideof the tube, sustains the globe in its elevated position and renders itimpossible to lower the globe except by applying sufficient force to theouter arm, h, of the lever to cause it to pass over the convex orcrowning side of the tube. lVhen this is done, the globe is low ered andguided by the hook G to its seat upon the air-chamber D. 9o

The inner arm, g, of the lifting-lever forms a guide-link which causesthe lower end of the globe to iind its seat upon the supporting-rim ofthe air-chamber D, so that upon lowering the globe the latter is seatedupon its support without requiring especial care or attention.

My improved lifting device is very simple in construction and verydesirable, especially in streetdanips, for sustaining the globe in anelevated position, thereby affording access to the interior of the globefor Cleaning the saine, and permitting the burner to be reaohed forlighting and extinguishing the lamp, and the latter to be removed fromthe frame, if required.v

I am aware that a lifting-lever engaging under the supporting-plate of averticallymovable globe is not new, and I do not claim -suchconstruction.

I claim as my invention l. The combination, With the tubular lamp` frameand the globe made vertically movable therein, of a spring lifting-leverpivoted to one of the side tubes and springing over the Convex side ofthe tube to lock the globe in its raised position7 substantially as setforth.

2. The combination, With the tubular lampframe, of a removableair-chamber, D, containing the oil-pot and burner, a looseverticallymovable globe, E, resting on said airehamber, a guide-linkpivoted to the tubular frame, and a globe-supporting hook hung to theinner end of the guide-link and extending under the bottoni edge of theglobe and upwardly on the inner side thereof7 said hook entering Withinthe rim of the air-ohamber When the globe is seated thereon,substantially as set forth.

Vitness my hand this 7 th day of June, 1887.

ELIAS C. GLAZIER.
